论文摘要
宇宙射线（CR）通量强度的突然大道调制（通常称为Forbush降低（FD））在我们对太阳 - 地球电动力学的理解中起着重要作用。在基于FD的分析中，FD幅度和时机的准确确切确定是棘手的问题之一。 FD鉴定因Cr昼夜各向异性而复杂。 CR各向异性可以增加或减少FD的数量和振幅。因此，重要的是要从FD识别之前从CR原始数据中删除其贡献。最近，尝试了傅立叶变换技术和FD-Location Machine的组合来解决这一问题。因此，通过过滤（FD1和ADV）和RAW（FD2）CR数据计算两个FD目录和振幅昼夜变化（ADV）。在当前的工作中，我们测试了FD1，FD2，ADV和太阳能物理特征之间的经验关系。我们的分析表明，两种类型的磁场间播（IMF）和地磁（DST）控制了CR通量强度降低的演变。
The abrupt aperiodic modulation of cosmic ray (CR) flux intensity, often referred to as Forbush decrease (FD), plays a significant role in our understanding of the Sun-Earth electrodynamics. Accurate and precise determination of FD magnitude and timing are among the intractable problems in FD-based analysis. FD identification is complicated by CR diurnal anisotropy. CR anisotropy can increase or reduce the number and amplitude of FDs. It is therefore important to remove its contributions from CR raw data before FD identification. Recently, an attempt was made, using a combination of Fourier transformed technique and FD-location machine to address this. Thus, two FD catalogs and amplitude diurnal variation (ADV) were calculated from filtered (FD1 and ADV) and raw (FD2) CR data. In the current work, we test the empirical relationship between FD1, FD2, ADV, and solar-geophysical characteristics. Our analysis shows that two types of magnetic fields-interplanetary (IMF) and geomagnetic (Dst) govern the evolution of CR flux intensity reductions.
